IPC: G06F3/12
Filed: 1980-02-08
Abstract: PURPOSE:To obtain a copy enabling a clear discrimination among colors of a display picture through a simple device, by securing a record of each color of the picture in a multigradation monochrome and in correspondence to each record concentration when a display color picture is recorded on a recorder via the video signal. CONSTITUTION:The incoming signals 1 of red, blue and green each are supplied to the signal process circuit 2, and the data quantized with sampling and control of the control circuit 4 is sent to the record head driving circuit 5 via the buffer memory 3. The circuit 5 is controlled by the block signal of the control circuit 4, and the heat generating element of the heat-sensitive record head 6 is heated for recording with the data of each block and in the seven different times of electric conduction corresponding to the red, blue, green, magenta, yellow, cyanogen and white each. And the paper is fed by driving the motor 9 with the motor driving circuit 8 and with every block. Thus the coloring concentration of the heat-sensitive recording paper is proportional to the time of electric conduction. As a result, a display color picture can be recorded in a multigradation monochrome by securing a correspondence between each color of the picture displayed on the CRT display and the recording concentration.

Title: Biological denitrificating apparatus
Inventor: HORII YASUO
IPC: C02F3/06
Filed: 1980-02-08
Abstract: PURPOSE: To facilitate nitrification and denitrification in the same tower or in the same vessel, by packing filters in the tower or vessel to form a biological filtering zone, and forming in the filtering zone both of an aerobic atmosphere part and an anaerobic atmosphere part.  
     CONSTITUTION: An original solution to be disposed is carried from an original solution tank 10 to an air-dispersing part 13 arranged in a nitrificating-denitrificating tower 12, by a pump 11. The solution is dispersed by the air fed from an air- dispersing pipe 6 to increase a dissolved oxygen amount. The solution flows upwards through a bacteria filtering zone. In this zone, soludge flocks are separated from the original solution by the filters, and the BOD, COD and SS values of the original solution are reduced also. Besides, nitrogen compounds such as NH 3 -N contained in the original solution are oxidized to NO 3 -N and NO 2 -N by reactions of nitrificating bacteria in the sludge which adhere onto the filter grains or exist in spaces among the filter grains. Owing to the oxidizing reactions, the lower layer 14 of the bacteria filtering zone is kept under an aerobic atmosphere, while the upper layer 15 is kept under an anaerobic atmosphere. Consequently, in the upper layer 15 of the bacteria filtering zone, the original solution is denitrificated by the actions of denitrificating bacteria living in the sludge within the filter grains.

Abstract: PURPOSE:To prevent a flaw and deformation while removing the lowering of operating efficiency generated by disturbing a semiconductor knockdown row by releasing the contact state of a hole section or a through-hole formed to a semiconductor knockdown anew transferred to the semiconductor knockdown row in the hole section. CONSTITUTION:Flat surfaces capable of being smoothly moved along flat surfaces 5, 5 are shaped to semiconductor assembly parts 2... as articles to be transferred and hole sections 7 utilized for an assembly process or transfer are formed to the flat surfaces. The tip section of a feed pin 3 annexed to a transfer path 1 is molded in a diameter capable of being fitted to the hole sections 7, and strokes thereof take values of 10-13 and 6. The strokes 6 carry the semiconductor knockdowns 2 to the end section of an unloader 4 by a stroke 11 required for the feed pin 3, and push and shift the row of the previously transferred semiconductor knockdowns 2.... The operation is conducted by the motion of the feed pin 3 brought into contact with the hole sections 7 shaped to the semiconductor knockdowns 2. The feed pin 3 is returned in the original direction once in the hole sections 7, and the contact states are released. Difference among friction coefficients at the contact positions and those among each semiconductor part is to some extent reduced by the operation.

Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To eliminate sticking by fitting a separate ring preventing sticking of opposed bellies between mountains when an object between a mountain and a valley is defined as a belly. SOLUTION: A bellows type suction pat 1 is constituted by fitting separate rings 10, 10 into a bellows 5 in which mountains 2..., valleys 3... are continuous via bellies 4.... In this case, the separate ring 10 is an elastic body in which the free length of a ring diameter D1 is a small diameter to expand in diameter till the mountains 2 are passed and to fasten the valleys 3. When an applying surface 6 is applied to a work and the inside of the bellows 5 is made negative pressure by an evacuation mechanism via a suction pipe used as also a supporting material in this bellows suction pat, the work approaches the suction pipe used as also a supporting material, and as a result, the bellows 5 becomes a compression state. But, because clearance always exists between the bellies 4, 4 by the actions of the separate rings 10..., these bellies 4, 4 each other are not stuck.

Title: Head for ink jet recording
Inventor: FUJII TADASHI
IPC: B41J2/16
Filed: 1980-02-12
Abstract: PURPOSE:To remove an ink knot at the outside of an ink injection nozzle by a method wherein a capillary groove, a space thereof decreases with the increase of a distance from the nozzle, is formed outside the nozzle, and an inwall of the capillary groove is made up so that an angle of contact to ink is specified. CONSTITUTION:A liquid chamber 3 for ink 2 is built up in a cylindrical nozzle holding member 1, and a nozzle plate 6 with a nozzle 5 is fixed to a stage section 4. A capillary groove 11 communicating a space section 8 and an outer circumferential surface is made up at an end surface of a flange 7 unified with the member 1. The capillary groove 11 is decided in a shape that a space of the groove decreases with the increase of a distance from the nozzle 5. After the ink 2 is injected, an ink knot 10 is formed in the space section 8 at the outside of the nozzle 5. After a fixed time passes, the ink knot 10 is absorbed to the capillary groove 11, and changed into an ink meniscus 13. The meniscus 13 moves downward and falls because an inwall 12 is set so that the angle of contact with the ink 2 is 90 deg. or less in the capillary groove 11.
